There’s virtually no information on the Tizen site that explains how someone is suppose to connect their Samsung Galaxy Gear S2 smartwatch to the TizenSDK. There is no USB plug on the watch. Plugging the dock in to my PC does nothing.

EDIT: After hours of searching I was able to find developer.samsung.com/technical-doc/view.do?v=T000000251. However, attempting to publish a sample wearable app to my device gave the following error:

Error code: SIGNATURE_INVALID
Error message: 
Command: /usr/bin/pkgcmd -i -q -t wgt -p “/opt/usr/apps/tmp/testuicomponentssample.wgt”
Management: Check author certificates in Preferences > Tizen SDK > Secure Profiles > Profile items.

When I looked up a video on how to sign my apps (youtube.com/watch?v=Xy2B-nlnprg), it tells me to go to the device preferences and grab the DUID. But that device preferences doesn’t show a DUID field.
